| Material Introduction | KED underground engineering protective material is composed of special hydrophobic polyurethane resin, siloxane, nano inorganic ceramics and other materials. It is a high-strength and high modulus anti-corrosion and anti-seepage material with high mechanical strength, high compressive strength, and can be constructed on wet substrates. It is an environmentally friendly material without VOC volatile substances |
| This technology is specifically designed for various underground engineering applications, such as non excavation repair of underground pipelines (anti-corrosion, reinforcement, anti-seepage); No need to excavate the road surface to replace new pipelines, reducing maintenance costs; Used for the reinforcement, repair, waterproofing, anti-seepage, and anti-corrosion of concrete buildings such as square ditches, pipe galleries, well chambers, water conveyance tunnels, and military caverns. The material can withstand high water pressure without seepage or bulging, and has excellent anti-corrosion performance, making it a new generation of concrete protection technology. Has more significant advantages than traditional photopolymerization materials |
| Traditional protective materials require the substrate to be dry, which cannot be achieved in underground pipeline construction. High pressure water flushing and dredging are required during underground pipeline construction, and even baking is difficult to meet the drying requirements, which is time-consuming and labor-intensive. KED technology can be used for construction on damp surfaces, and when combined firmly, it solves a major problem. |
| This technology can be applied to underground utility tunnels, underground trenches, and various aging well chambers. There are already a large number of mature applications available now. According to different application scenarios, there are corresponding specialized materials with different performance. |
